Ukupakishwa kwamabhontshisi wekhofi akugcini nje ngokubukeka, kodwa futhi kuyasebenza. Ukupakishwa kwekhwalithi ephezulu kungavimba umoya-mpilo ngokuphumelelayo futhi kwehlise isivinini sokuwohloka kwephunga likabhontshisi wekhofi.
Izikhwama eziningi zikabhontshisi wekhofi zizoba nesici esiyindilinga, esifana nenkinobho kuso. Cindezela isikhwama, futhi iphunga lekhofi lizobhobozwa ngembobo encane ngenhla "kwenkinobho". Le ngxenye encane enomumo "wenkinobho" ibizwa ngokuthi "i-valve yendlela eyodwa yokukhipha umoya".
Ubhontshisi wekhofi osanda kugazingwa kancane kancane ukhipha isikhutha, futhi lapho ugazinga usiba mnyama, kuphuma isikhutha.
Kunemisebenzi emithathu ye-valve yokukhipha indlela eyodwa: okokuqala, isiza ubhontshisi wekhofi ukuba uphele, futhi ngesikhathi esifanayo ivimbela i-oxidation yamabhontshisi wekhofi okubangelwa ukubuya komoya. Okwesibili, ohlelweni lokuthutha, gwema noma unciphise ingozi yokulimala kokupakisha okubangelwa ukunwetshwa kwesikhwama ngenxa yokuphuma kobhontshisi bekhofi. Okwesithathu, kwabanye abathengi abathanda ukuzwa iphunga, bangathola iphunga elithakazelisayo likabhontshisi wekhofi kusengaphambili ngokucindezela isikhwama sikabhontshisi.
Ingabe izikhwama ezingenawo ivalve yokukhipha enye indlela azifanelekile? Hhayi ngokuphelele. Ngenxa yezinga lokuthoswa kukabhontshisi wekhofi, ukukhishwa kwe-carbon dioxide nakho kuhlukile.
Ubhontshisi wekhofi ogazingiwe omnyama ukhipha igesi eningi ye-carbon dioxide, ngakho-ke i-valve yokukhipha umoya yendlela eyodwa iyadingeka ukusiza igesi ukubaleka. Komunye ubhontshisi wekhofi othosiwe okhanyayo, ukukhishwa kwe-carbon dioxide akusebenzi kangako, futhi ukuba khona kwe-valve yendlela eyodwa yokukhipha akubalulekile kangako. Yingakho, uma wenza ikhofi elithelwe phezu, ama-roast amancane "amakhulu" kunobhontshisi omnyama ogazingiwe.
Ngaphezu kwe-valve yokukhipha indlela eyodwa, enye inkomba yokulinganisa iphakheji yinto yangaphakathi. Ukupakishwa kwekhwalithi enhle, isendlalelo sangaphakathi ngokuvamile siyi-aluminium foil. I-aluminium foil ingavimba kangcono umoya-mpilo, ukukhanya kwelanga kanye nomswakama ngaphandle, idale indawo emnyama yamabhontshisi wekhofi.
